12 years ago 3 1/2 years after I had a prostatectomy my PSA hit .2 and I was put on salvage radiation. It’s interesting that you are going to have 7 1/2 weeks of radiation. That’s what I had 12 years ago. These days they’re talking about doing this is in 20 visits. This may be due to where you are going, not being up-to-date.

Having salvage radiation gave me another 2 1/2 years before it came back again.

The problem is, some doctor say don’t get salvage radiation because it doesn’t work out in many cases, Just get PET scans regularly and zap the metastasis. If only this answer really worked all the time, It doesn’t.

Here’s what the medical community says about getting treated with salvage radiation. As you can see from this information, waiting to have treatment can be very damaging to your future.

From Ascopubs about what PSA to do salvage radiation.
≤0.2 ng/mL:
Starting at this level maximizes disease control and long-term survival. Patients treated at PSA < 0.2 ng/mL achieve higher rates of undetectable post-SRT PSA (56-70%) and improved 5-year progression-free survival (62.7-75%).
Delaying SRT beyond PSA ≥0.25 ng/mL increases mortality risk by ~50%.

0.2–0.5 ng/mL:
Still effective, particularly for patients with low-risk features (e.g., Gleason ≤7, slow PSA doubling time). The Journal of Clinical Oncology recommends SRT before PSA exceeds 0.25 ng/mL to preserve curative potential.

0.5–1.0 ng/mL:
Salvage radiation remains beneficial but may require combining with androgen deprivation therapy (ADT) for higher-risk cases.
